Listers, I am trying to use TargetPro in combination with MapInfo and CallingAreaInfo to create a population coverage map. I keep getting coverage estimates that sum to far more people than exist in the United States! I am fairly sure that I am getting overlapping coverage area. Is there any way to eliminate the overlap? I am using polygons created by CallingAreaInfo, changing them to regions, and then running them through TargetPro. Any help is appreciated...thanks in advance. Jonathan Watson
